Thanks ohnomis for the prefix version "++points" . ;)
I think you should mark the thread as solved.

Which compiler are you using? Strange error :O

Do not initialize steps with command[++cmd], this will surely increment cmd before it even enters the switch statement. Just initialize the steps variable with any legal value. It will be better if...

For prime function, have a look at this thread -

And for random function, have a look at this thread - ...

I think you can declare and intilialize steps after the function "processTurtleMoves" declaration.

void TurtleGraphics::processTurtleMoves( const int commands[] )
{
int steps=0;
.... .. .. ...

Function call should be like this

func(array_name); //where array_name is the name of your array.

You should pass the array without any index, because passing with an index makes the value at...

Thanks VernonDozier and Salem. :)

cmath different in visual c++ and dev c++ ? Sorry, I know i ask a lot of questions but i'm Curious.

Thanks Salem for your answers. :) But DEV-CPP compiled the code with no error, whereas with the same code Visual C++ gave the above error.

When i compiled the above code in Visual C++, I got the following error error C2668: 'sqrt' : ambiguous call to overloaded function Though I understood the error, but the same code gave no errors...

I think using system("pause"); is not recommended.

Thanks VernonDozier for your concern. :) Actually after the Lerner's post, i realized what was Salem pointing at. "I dont got it" at the time when Salem gave me the hint, but after lerner's post it...

Salem gave me the hint, but I dont got it. :( Thanks Lerner for helping.

Any other tips for efficiency?
There is only 1 even prime number i.e 2.

Thanks Salem for help, I think you really hate those who use "void main()" and you love "int main()" as your avtar and line under name says :D

Why void main is deprecated in ISO standards? Where can i get a brief overview of the ISO C++ standards?

I know about namespaces and the new standards i.e #include<iostream> , but ya my compiler "Turbo C++ v3.0" is old and dont understands the new formats like namespaces and the new style header files....

But, i think a doc file is different form a simple text file so this should not work.

I noticed that recheck , but i did something wrong in the second loop while correcting that. Therefore to avoid further error, i implemented it this way.
Thanks VernonDozier for optimized code. :)

Does that mean i wrote a good code .. Hurray!! :twisted:

Thanks William :) for your suggestions. I liked them. Can you tell me more about size_t (is it the longest unsigned integer?) And are there any suggestions for shorting the code, bcoz i think i coded...

This is strstr() function made by me as given in the practice problem.

char *p=NULL;
l1=strlen(s);
l2=strlen(ss);
